如何在 Cargo.toml 中启用每个平台的 crate 功能? [英] How to enable crate features per-platform in Cargo.toml?

问题描述

如何在 Cargo.toml 配置中启用每个平台的 crate 功能?我试过两种方法，都不行.

How do I enable crate features per-platform in a Cargo.toml configuration? I've tried two methods, neither of which work.

方法一:

[target.'cfg(windows)'.dependencies.rusqlite]
version = "0.19.0"
features = ["bundled"]

[target.'cfg(unix)'.dependencies.rusqlite] # same behavior with cfg(not(windows))
version = "0.19.0"

方法二:

[target.'cfg(windows)'.dependencies]
rusqlite = { version = "0.19.0", features = ["bundled"] }

[target.'cfg(unix)'.dependencies]
rusqlite = { version = "0.19.0" }

我试图仅在 Windows 平台上使用捆绑"功能，但无论我尝试以哪种方式配置货物，在 Ubuntu 系统上构建时，它总是添加捆绑"功能.

I'm trying to use the 'bundled' feature only on Windows platforms, but regardless of which way I try to configure cargo it always adds the 'bundled' feature when building on an Ubuntu system.

是否可以只在一个平台上启用功能?

Is it possible to enable features only on one platform?

推荐答案

是否可以只在一个平台上启用功能?

Is it possible to enable features only on one platform?

不，这是不可能的，因为 货物问题 #1197.

No, it is not possible, due to Cargo issue #1197.
